Using Perspective plugin in RCP application

[evfool]

Hello there.
I have a problem: I have an empty RCP application, with an empty default perspective, and a perspectiveBar
I would like to create plugins, which, copied into the directory of the exported RCP apps plugins directory will show up in the Add Perspectives/Other dialog box
I have created such a plugin with a wizard, the Release Engineering perspective, that works when I start it in an Eclipse Workbench, it shows up in the Add perspectives dialog ...
I suppose i have to add something to the RCP app... some extension point maybe?
Thanks for your answers in advance
